Yes, only banks stoop that low ...

You don't imagine that banks print their own statements, do you???? It's
all subcontracted out.

And I don't think they use laser printers, far too slow, with all
that fusing nonsense. Certainly my Barclays statement is decidedly
fuzzy, dotty and grey, rather than the pin sharp black you get from a
laser.

Lets do some scaling maths again. Say 5 million, 4 page both sides
printed, statements per month. That's 40,000,000 sides/month, 30 day
month, means 1,333,333 sides/day or 15.43 sides/second, Second not
minute...


One magnetic drum printer could manage that, but you need about four men
to operate it, loading and unloading paper.

Newspapers print near that speed and you can print variable content on
some of them even if most content is fixed plates. They use rolls
weighing more tha a ton and are a lot bigger and more expensive.

Of course no bank is likely to have only one printer and they may well
outsource it to one or more print firms with lots of printers.
